The Definition of Misfeed
Is a failure of the next round to completely enter the chamber. Misfeeds and failures to feed are very similar, a
failure to feed is a round that never even leaves the top of the magazine, while a misfeed is a
round that leaves the magazine but does not enter the chamber.

The point at which you are aiming the firearm at.
A sub-field of ballistics, is the study of the behavior of a projectile when it hits its target.
A middle position for an external hammer that effectively provides a safety function. With a firearm with non-rebounding hammers,
when on half-cock, the firing pin will not rest on the firing-pin.
A type of action used primarily for single shot rifles whereby some kind of lever actuates a breechblock, moving it downwards in a vertical recess to expose the chamber.
May have visible or enclosed hammer. For any given barrel length, it allows a shorter overall rifle length compared to a bolt action because no space is
taken up by the forward-and-back cycling of the bolt. Most of the better British makers produced them in limited numbers around the turn of the last century,
the Farquharson being the most iconic. Perhaps the best-known falling block action today is the Ruger No.1.

Types of ARs include AR-15, AR-10 and AR-7.
A double-barrel shotgun, with relatively tight choke boring and a relatively high-combed stock used for shooting live pigeons
(euphemistically known as flyers) which normally rise when released. To better absorb recoil, a pigeon gun is normally heavier than
a field gun as one shoots heavy loads and walks only a little. Because of the inevitable expense of this shooting discipline,
pigeon guns are often built to a high standard of quality and reliability in deluxe grades with highly figured walnut stocks and fine engraving.

When someone says "an AK" they are usually referring to the AK-47 rifle which was originally designed in Russia by Mikhail Kalashnikov.
